I am using the 7.1.5463.1 version of DayPilot.Web.Mvc.dll
I am using the scripts from 11/20/2012
I have created a sample application to demonstrate the behavior, but it is too big to upload.
When selecting a week in the navigator section, the "linked" calendar is not displaying the dates of the selected week.
Also, if you check the e.Data["start"] value in the OnCommand event, it is actually returning the date of the previous week.
It seems to work correctly in the aspx sample.
